FastHTTP Extension brings the full FastHTTP development experience into VS Code — project scaffolding, route explorer, inline diagnostics, and CodeLens actions.

Key features:

• Create Project — scaffold a ready-to-run FastHTTP project from the Command Palette in seconds.
• Route Explorer — sidebar panel showing all @app.get/post/... routes across your workspace, grouped by file. Click any route to jump to its definition.
• CodeLens — ▶ Run and Copy URL actions appear above every route decorator.
• Diagnostics — inline errors and warnings for missing async def, missing -> ReturnType, and missing resp: Response parameter.
• Smart detection — only activates on files that actually instantiate FastHTTP() or Router(). No false positives from FastAPI or other frameworks.

Requirements

• VS Code ^1.85.0
• fasthttp-client installed in your Python environment to run generated projects.

Installation

Install from the VS Code Marketplace:

1. Open VS Code
2. Press Ctrl+P (or Cmd+P on macOS)
3. Run ext install ndugram.fasthttp-extension

Or search FastHTTP in the Extensions panel.

Usage

Create a project

1. Open the Command Palette (Ctrl+Shift+P / Cmd+Shift+P)
2. Type FastHTTP: Create Project
3. Enter a project name
4. Select a folder where the project will be created
5. Choose to open the project in a new or current window

Generated structure

my-project/
├── main.py
├── requirements.txt
└── pyproject.toml

main.py

from fasthttp import FastHTTP
from fasthttp.response import Response

app = FastHTTP()


@app.get(url="https://httpbin.org/get")
async def get_data(resp: Response) -> dict:
    return resp.json()


if __name__ == "__main__":
    app.run()

Route Explorer

Open the FastHTTP panel in the activity bar to see all routes in your workspace:

FASTHTTP ROUTES
└── main.py  3 routes
    ├── GET      https://httpbin.org/get        get_data()
    ├── POST     https://httpbin.org/post       post_data()
    └── DELETE   https://httpbin.org/delete     delete_data()

Click any route → jumps to the decorator in the file. Use the ⟳ button to refresh manually.

Diagnostics

The extension highlights handler errors inline:

Problem	Severity
def instead of async def	⚠️ Warning
Missing -> ReturnType annotation	❌ Error
Missing resp: Response parameter	⚠️ Warning

Run the generated project

$ pip install fasthttp-client
$ python3 main.py

You will see output like:

16:09:18.955 │ INFO │ fasthttp │ ✔ FastHTTP started
16:09:19.519 │ INFO │ fasthttp │ ✔ GET https://httpbin.org/get [200] 458.26ms
16:09:20.037 │ INFO │ fasthttp │ ✔ Done in 1.08s
